וַיִּסְע֖וּ מִסֻּכֹּ֑ת וַיַּחֲנ֣וּ בְאֵתָ֔ם בִּקְצֵ֖ה הַמִּדְבָּֽר׃
And they took their journey from Succoth, and encamped in Etham, in the edge of the wilderness.
Targum Jonathan on Exodus
And they journeyed from Succoth, the place where they had been covered with the clouds of glory, and sojourned in Ethan, which is on the side of the desert.
